| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Locally repairable codes whose erased code word symbols can be repaired from other symbols have attracted a good deal of attention in recent years. $(r_u,delta_u)_{uin[s]}$-locally repairable codes with multiple localities, which are an extension of general locally repairable codes, can repair $delta_u$ symbols erased simultaneously from the set consisting of at most $r_u$ symbols. Though an upper bound on the minimum distance of this code was given by Chen et al., there are few explicit constructions of the optimal codes. In this paper, we propose explicit constructions of the optimal codes with multiple localities based on those of general locally repairable codes introduced by Tamo and Barg. |
